Bought these strips...did the entire treatment and saw little to no difference. As a college student who couldn't afford these in the first place...I am so sad to have made this purchase. I don't even have a receipt to get my money back. DO NOT recommend. :(

Great product, my mom says she can really see the difference in just one use! I don't use these that often but every once in a while works well for me. My only issue is that my teeth appear patchy white after but that goes away after a few days and it can make your teeth sensitive warning!

I've tried these in the past and even thought I could really see the difference, these strips left my teeth feeling extra sensitive for 1-2 days afterwards. These work really well but if you have sensitive teeth, I don't recommend. It will cause your teeth to ache afterwards.

My teeth got so much whites after only 5 strips. I wish the upper teeth strip was a little bit longer. I usually whiten my teeth before going to bed because my lower teeth are quite sensitive after using these strips but if I do it before the sleep I wake up the next morning and my teeth don't feel sensitive at all.

This is by far the best white strips on the market. I've been using these for about 3 years and my teeth have never been white. They are absolutely amazing, go on easily and stay on, and only make my gums slightly sensitive- and that's only if I put them on afternkot having done so for a while. The picture is after 6 months of use about 2 times a week for the first month, then once a week after that- no editing!!

I've used these in the past and had great results. My teeth remain white and every once in a while I will re use for maintenance. The only con is the sensitivity. I would honestly use them more often if they didn't cause my teeth to feel so uncomfortable. The sensitivity goes away within about a week of ending use though.

I really like this product. I drink a lot of coffee and I love red wine both of which can cause teeth staining. I use these strips 3 times per week and I get great comments on my smile, especially in photographs. I've gotten my daughter and fiance to use these too.

I use these with the crest whitening tooth paste and the combination just works really well. This pack comes with 12 pairs of strips (top and bottom) and they work so well I started by doing 12 treatments straight but now I just use one every once in a while.

Not comfortable at all. The strips slide around so you have to make sure you're not really doing much, and makes me roam at the mouth a bit (lol) always quit before using consistently because of the discomfort so I'm not sure how well they actually work

I just recently started using these and I've only done it a couple of times but I haven't had any problems with it. I haven't seen any clear results but I'm giving it some time to work. Overall, it seems like a decent product but clear results aren't quick.
